A lot of people have trouble with this one.

You know those relationships that start out going a million miles an hour? The ones where you stay locked in their apartment for three days straight staring into each other's eyes? The ones where you start talking about spending your whole lives together after only three months? Those loves are hot, and fiery, and full of passion.

They're also usually the first to go crashing into a wall and exploding into a million pieces.

Love is a roller coaster — and it's supposed to be.

But one of the hardest lessons to learn is how to apply brakes to that roller coaster. You need to know when to speed up and when to slow down. When to go all in and when to pull back and take things slow.

Because the truth is, without at least some brakes on that train, it's going to go faster, and faster, and faster, and you're going to skip all the little things you needed to learn and acknowledge about each other along the way.

And by the time those things matter, it will be too late.
